1.1 This European Standard applies to machines for the manufacture of constructional products from concrete and/or calcium silicate examples of which are listed in annex A of this part. It gives concepts and general and common requirements for the design, operation and maintenance of such machines. 1.2 This European Standard deals with hazards listed in Clause 4 which can arise during the operation and maintenance, including the interfaces, of the machines for the manufacture of constructional products from concrete and calcium silicate, when carried out as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. Part 2 to 8 of this standard give additional specific requirements and therefore have to be applied together with this part.1.3 The preparation of concrete and/or calcium-silicate mixture and the transport from the mixer to the manufacturing plant are not part of this European Standard (see EN 12151:2007). The equipment for the transport and handling of formed products, other than the integrated transport system, is not covered by this standard. 1.4 At the time of drafting, machine specific noise test codes for EN 12629-2 to -8 are not available to fulfill the requirements of 5.7.2 and 7.4.2. When they are available, they will be incorporated in these standards. 1.5 This document is not applicable to machines for the manufacture of constructional products from concrete and/or calcium silicate, which are manufactured before the date of publication of this document by CEN.
